Artemis II Launch Delayed as Cold Weather Echoes Challenger Anniversary
Florida’s recent cold snap, with temperatures forecast to potentially reach -6°C, has prompted NASA to postpone a critical test of the Space Launch System (SLS) rocket for the Artemis II mission, raising eerie parallels to the 1986 Challenger disaster. The delay underscores the challenges of returning humans to the moon, a goal now tentatively set for a launch window beginning February 8th.
The postponement centers around the “wet dress rehearsal,” a crucial examination of the rocket’s fuel pumping systems using cryogenic fuel – liquid hydrogen and oxygen. According to sources at the Kennedy Space Center, the test, originally scheduled to begin February 2nd at 9:00 PM ET (February 3rd at 2:00 a.m. CET), has been called off due to the extreme conditions.
“It’s freezing, we’re calling off the general test and the start,” a live feed from Launch Complex 39B (LC-39B) reportedly stated.
The timing of the weather event, coinciding with the 40th anniversary of the Challenger tragedy, has not been lost on observers. The SLS rocket, heavily influenced by the Space Shuttle program, currently stands on the same LC-39B ramp where the Challenger was prepared for its ill-fated flight.
The Artemis II mission aims to send a four-person American-Canadian crew into lunar orbit – a feat not accomplished in over fifty years. Despite the delay, NASA remains optimistic. “If all goes according to plan, in less than two weeks humans will be back on the moon, and thanks to a special flight path, even further than the days of the Apollo missions!” one official stated.
Preparing for Lunar Return
The 98-meter-tall SLS rocket was moved to the LC-39 ramp approximately two weeks ago, transported by a conveyor belt over a distance of seven kilometers along the Atlantic coast. The Orion spacecraft, perched atop the SLS at a height of approximately 100 meters, requires constant heating to prevent freezing, as it is not designed to withstand the current frigid temperatures. The service module of Orion is based on the European ATV supply ship for the International Space Station (ISS), while the crew module draws inspiration from the Apollo-era command module.
During the wet dress rehearsal, NASA will simulate a full launch countdown, stopping just 30 seconds before engine ignition. Any issues encountered during this test could result in a delay of at least one day to the actual launch. The SLS utilizes a hydrogen-powered main rocket, complemented by two solid-fuel side boosters – a design element inherited from the Space Shuttle, and visually reminiscent of the former orange external tank.
Public Access and Ongoing Updates
NASA has established a live broadcast from the LC-39B ramp on YouTube, providing intermittent updates on the preparation process. A dedicated broadcast is planned for the wet dress rehearsal, offering views from multiple cameras.

For a deeper dive into the mission, a special Artemis II podcast is available, featuring discussions on:
- 03:08 – A comeback we couldn’t believe
- 08:38 – Crew and cultural heritage
- 12:24 – SLS and Orion
- 30:56 – Route profile
- 43:52 – Artemis 3 and the future
The current situation highlights the inherent risks and complexities of space exploration, even with decades of advancements. While the delay is a setback, it underscores NASA’s commitment to safety and the meticulous preparation required for humanity’s return to the moon. The question remains: will the weather cooperate, and will Artemis II reignite the public’s fascination with space travel?
